- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
- Harvest — picking time — check ripeness every few days.

Questions
Jiaogulan questions, answered straight.
Why isn't my jiaogulan fruiting?
Most often: it has no genetically distinct partner nearby. Jiaogulan can't pollinate itself — dioecious; leaves are the main harvest. Plant a second, unrelated one nearby; two different cultivars, or a cultivar plus a seedling, is the classic pairing.
Is jiaogulan safe for kids and pets?
With care. Caution: medicinal tea; may interact with diabetes, blood-pressure, blood-thinning, or immune medications Site it accordingly if children or pets roam the garden. This is general reference, not medical or veterinary advice — call a vet or poison control if something has actually been eaten.
When do you harvest jiaogulan?
Leaves from summer to frost; dry for sweet herbal tea.
